Abstract

Articles of athletic garments, particularly sports bra and methods of treating the athletic garments with a shear thickening fluid (STF) are disclosed. The athletic garment comprises a STF treated fabric. The STF treated fabric in contact with the wearer's body part restricts movement of the body part when the shear stress exceeds the shear stress threshold value and stretches and conforms to the wearer's body part when the shear stress is less than the shear stress threshold value. The STF treatment method may include immersing the untreated fabric in a diluted STF bath, metering an amount of the fluid on the fabric, and removing the diluent from the treated fabric.

First claim

What is claimed is:

1. A sports bra, comprising:
a front section configured for covering at least a portion of a wearer's anterior torso, the front section comprising a non-planar region for supporting a wearer's breasts; and
a rear section configured for covering at least a portion of the wearer's posterior torso,
at least one of the front and rear sections further comprising:
a fabric treated with a shear thickening fluid, wherein the shear thickening fluid comprises particles dispersed in a fluid medium, wherein the size of the particles ranges from 5 nm to 50 um.

2. The sports bra of claim 1 , wherein the particles are selected from a group consisting of: silicon dioxide, titanium dioxide, calcium carbonate, and polymers.

3. The sports bra of claim 1 , wherein the front section consists solely of the fabric treated with the shear thickening fluid.

4. The sports bra of claim 1 , wherein the rear section consists solely of the fabric treated with the shear thickening fluid.

5. The sports bra of claim 1 , further comprising a pair of shoulder straps extending upwardly from the non-planar region, wherein the pair of shoulder straps are treated with the shear thickening fluid.

6. The sports bra of claim 1 , further comprising a bottom band encircling the wearer's torso below the wearer's breasts, wherein the bottom band connects the front and the rear sections along a girth of the wearer's torso.

7. The sports bra of claim 1 , wherein the front and the rear sections are connected using a method selected from the group consisting of: stitching, zipping, gluing, snaps, hook-and-eye, and hook-and-loop.

8. The sports bra of claim 1 , wherein the fabric is selected from the group consisting of: cotton, polyester, nylon, spandex and combinations thereof.

9. The sports bra of claim 1 , wherein the fabric treated with the shear thickening fluid further comprises a water-repellent coating.

10. An article of sportswear, the article comprising:
a fabric treated with a shear thickening fluid having a shear stress threshold value, wherein the shear thickening fluid comprises particles dispersed in a fluid medium, the treated fabric when secured on a wearer's body part comprising:
a first portion of the treated fabric in direct contact with the wearer's body part for supporting the wearer's body part,
wherein the first portion of the treated fabric stretches and conforms to the wearer's body part when a shear stress in the first portion of the treated fabric is less than or equal to the shear stress threshold value,
wherein the first portion of the treated fabric restricts movement of the wearer's body part when the shear stress in the first portion of the treated fabric is more than the shear stress threshold value; and
a second portion of the treated fabric not in direct contact with the wearer's body part.

11. The article of claim 10 , wherein the article is a sports bra.

12. The article of claim 10 , wherein the article is an article of footwear.

13. The article of claim 10 , wherein the particles are selected from a group consisting of: silicon dioxide, titanium dioxide, calcium carbonate, and polymers.

14. The article of claim 10 , wherein the size of the particles ranges from 5 nm to 50 um.

15. The article of claim 10 , wherein the concentration of particles in the fluid medium ranges from 5% to 90% by weight.

16. The article of claim 10 , wherein the fluid medium is selected from a group consisting of glycols, silicone oils, and hydrocarbon fluids.

17. A sports bra, comprising:
a front section configured for covering at least a portion of a wearer's anterior torso, the front section comprising a non-planar region for supporting a wearer's breasts; and
a rear section configured for covering at least a portion of the wearer's posterior torso,
at least one of the front and rear sections further comprising:
a fabric treated with a shear thickening fluid, wherein the shear thickening fluid comprises particles dispersed in a fluid medium, wherein the concentration of the particles in the fluid medium ranges from 5% to 90% by weight.

18. The sports bra of claim 17 , wherein the front section consists solely of the fabric treated with the shear thickening fluid.

19. The sports bra of claim 17 , wherein the rear section consists solely of the fabric treated with the shear thickening fluid.

20. The sports bra of claim 17 , wherein the fabric treated with the shear thickening fluid further comprises a water-repellent coating.
